I don't think it is a good idea to sell off your bitcoin and use the money to invest in some altcoins. I know you are aware that altcoins are not reliable at all. So the best advice I will give you is to hold your bitcoin, and with patience, you will surely make reasonable profits from it. Don't be so eager to make quick money in the crypto industry, because I believe your aim may be that you want to make quick money, which is why you are thinking of selling your bitcoin and investing in alternative coins. I am not fully condemning all alternative coins, but the truth is that 98% of them are pump and dump coins. and you may likely lose your money if you invest in them.
